Application iled December 11, 1893. Serial No. 493,445. (No model.)

To @ZZ whom it may concern:

Be it known `that I, EMIL H. FICKINGER, of Canton, inthe county of Stark and State of Ohio, have invented certain new and useful Improvements in Machines for'Making Conductor-Pipes; and I do hereby declare the'fol'- lowing tobe a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which itpertains to make and use the'same.

My invention relates to improvements in machines for making conductor-pipes, the machine being more especially designed for making corrugated conductor-pipes; and it consists in certain features of construction, and in combinations of parts hereinafter described and pointed out in the claims.

Y In the accompanying drawings, Figures l and 2 are elevations of opposite ends of the machine, respectively, showing, in transverse section, the track and guide along which the machine travels, -stationarydie or form, and the conductor-pipe P mounted upon said form or die. Fig. 3 is a side elevation of the machine. Fig. 4 is a section on line 4-4, Fig.v

1. One of the corrugating-dies is shown-removed in Figs.' 1 and 4. Fig. 5 is a section on line 5-5, Fig. 2, and Fig. 6 is a section on line 6-6,Figs.2 and 5. Fig..7 is a transverse section of the conductor-pipe before the latter is'seamed and corrugated.` Fig. 8 is-a transverse section of the pipe lafter being' corru-y gated, but before being completely seained.

Fig. 9 isa transverse section of the finished' pipe. y

The machine comprises two heads, A and B, located a suitable interval apart andponnected or tied together at the top and bottom by one or more cross-pieces, C, and the machine, at the bottom, is provided on each side with a pair of grooved wheels,-D,that engage the rails E of the track alongLwhich" the machine is adapted to travel, and the machine, at the top, is provided with a pair of grooved wheels G that are located preferably centrally between the two pairs of wheels D and en` gage a guide, H,`that is arranged yparallel with track E E and is supported from above in any Each of heads A and B has a` central hole or opening, 'a and b, respectively, said holes kbeing of such size as to iaccommodate the location of the stationary die or form I, upon which the pipe to beoorrugated and seamed is mounted and also to accommodate the location and operation of the adjustable dies K (hereinafter described) employed, to co-operate'with form or die I, in

ycorrugating the conductor-pipe.

The die or form I, upon whichV the pipe to be corrugated and seamed is mounted, consists, as heretofore, preferably of a metallic beam'that has'such external contour as is desired to be given to the conductor-pipe, the same having longitudinal external corrugations, I', into which the metal of the pipe to be corrugated'is pressed by means of dies K.

I provide, preferably, dies that are adjustable radially relative to the work, in order to take up the wear of the dies from time to time,

.and to accommodate diferent depths of corrugations.

My improved corrugating-dies consist, respectively,of a wheel having a convex periphery and supported byV and at the Vinner end of a radially arranged slide K ythat is adjustable endwise of a slide-way K2-formed in and arranged radially of the supporting-head, i

the slide having, preferably, at its inner end, two inwardly-proj ecting lugs or ears Kito and between which the rotary die is pivotally secured.

One' or both heads AandB of the machine are provided, respectively, with as many corr'ugating dies as it is desired to form corrugations in the conductor-pipe. The die-carrying slides are secured, respectively, to the respective supporting-head, preferably by c I prefer to employ two series of corrugat-v ing-dies, one series upon theouter side of the Ico one head A, and another series upon the iu` ner side of the other head B as shown.

The pipe is mounted upon die or form I with the portion of the pipe to be seamed uppermost. The portions of the pipe that overlap each other, where the seam is to be formed, are preferably pressed more or less together before the seam is completely closed, and I, therefore, provide one or both heads of the machine with a radially adjustable roller, L, for operating upon said portions of the pipe, said roller being supported from a slide L that is carried by and adjustable radially relative to the work in substantially the same manner as the slides that carry the corrugating-dies.

The seaming or seam-closing apparatus comprises a grooved wheel or roller M rotatably supported at the lower end of a swinging frame or block, m, that is pivoted, at or near its upper end, as at m', to and between laterally and outwardly-projecting and vertically-arranged ianges N of a slide, N, that is adjustable endwise of a vertical slide-way n formed in a plate u that -is secured, preferablyby means of bolts or screws n2, tothe outer side of head B. Plate n', at the top, is provided with two laterally and outwardlyprojecting lugs or members n3 that are located at opposite sides of slide N', respectively, and are connected by means of cross-piece n" that affords bearing for a screw, O. The screw engages a correspondingly-threaded hole in member n4 and is operatively connected with slide, N, the slide, at the top, having preferably a laterally' and outwardly-projecting and horizontally arranged liange, N2, that is bored vertically for receiving the lower end of screw O, and the portion of the screw that extends into said iiange being provided with an annular groove O' that is engaged by a set-screw O2 extending into fiange N2 from the outer edge of said flange.

By the construction just described, it will be observed that the screw can be turned in the one direction or the other butcannot become displaced endwise from the slide; that the slide and the scathing-Wheel or roller carried thereby are adjusted toward and from the work according as the screw is turned in the one direction or the other. The screw is adapted to be secured in the desired adj ust ment by means of a nut Q mounted thereon at the top side of member n4.

The machine,it will readily be understood, is moved in the one direction during the corrugating-operation and in the opposite direction during the scanning-operation.

Because the seaming-wheel or roller is capable of swinging outwardly, it follows that the same will operate idly during the corrugating operation of the machine, and to positively prevent the seaming-roller from closing the seam during the corrugating operation, the frame or block that carries said roller, is preferably weighted at its inner side, as at m2. The outer side of slide N however,

seam-closing operation.

forms a stop to prevent the seaming-wheel or roller from being swung inwardly, as shown very clearly in Fig. 5, and said wheel or roller will, therefore, be properly held to its work during the seaming-operation. The axis of the elearning-wheel or roller is preferably located just inwardly or rearwardly of the pivotal bearing of the frame or block that carries said wheel or roller, as shown in Fig. 5, which feature is clearly indicated by dotted lines R R drawn vertically and parallel with each other through the axis of the wheel'or roller, and axis of the swingingframe or block, respectively. By having the axisof the seaming-wheel or roller located a trifle rearwardly of the pivotal point of the frame or block that carries said wheel or roller, in conjunction with the stop formed by the outer side or slide N', it is obvious that the seaming-wheel or roller will posi tively be held to its work during the seaming or The seaming-wheel or roller cannot be moved inwardly by reason of said stop and any tendency of the wheel or roller to swing outwardly during the seaming operation will, owing to the peculiar location of the axis of said wheel or roller, relative to the axis of the frame or block that carries the wheel or roller, result in a still larger pressure upon the portions of the pipe to be seamed.

It is sometimes desirable or found necessary to adjust plate n' that bears the slideway of the seaming-roller-carrying-slide horizontally to bring the scanning-wheel or roller into accurate adjustment laterally of the machine relative to the location of the seam. To this end, I elongate holes a5, in said plate and through which the securing-bolts n2 pass, in a horizontal direction, and hence, by loosening said bolts plate n can be adjusted horizontally, and secured in the desired adjust ment by retightening the bolts.

It is also important to provide a hrm bearing or support for the conductor-pipe, and the die or form upon which the pipe is mounted, j

at a point diametrically or approximately diametrically opposite the location of the seaming-wheel or roller. The bearing or support referred to consists preferably of a wheel or roller, S, whose peripheral surface has such contour as to nicely t the adjacent surface of the conductor-pipe. This wheel or roller is revolubly supported at the upper end of a slide, S', that is adapted to be adj usted end- Wse, by means of a screw, S2, in a vertical slideway S3 formed upon plate S4 that is suitably secured to the outer side of head B of the machine. The construction whereby the adjustment of said slide S is effected, is substantially the same as that already described in connection with the adjustable feature of the seaming-wheel or roller, and plate S4 is also preferably adjustable horizontally in the same manner as plate n. I would also remark that the corrugating-dies of each series of corrugating-dies are preferably removable IIO 'iss
